Design & Planning Management in Bexley & Kent

Professional Design Coordination and Planning Support for Building Projects

Successful building projects don’t start on site — they start with clear planning, good design coordination, and a well-managed approval process. Poor preparation often leads to delays, budget overruns, and unnecessary stress. That’s why having experienced professionals manage the design and planning stages is just as important as the construction itself.

At P J Dunbar Builders Ltd, we provide design and planning management services for domestic and commercial projects across Bexley, Bexleyheath, Sidcup, Dartford, Eltham, Welling, Orpington, and the wider Kent area. With over 30 years of experience, we help clients navigate the early stages of their project with clarity, structure, and confidence — ensuring everything is properly prepared before work begins.

Whether you’re planning an extension, renovation, new build, or commercial project, we coordinate the right professionals, manage the process, and keep everything moving in the right direction.

Our Design & Planning Management Services

Design and planning can be complex, particularly for homeowners undertaking a project for the first time. Our role is to simplify the process and ensure every stage is handled correctly.

Design Coordination & Technical Preparation

We coordinate with architects, designers, and structural engineers to ensure drawings, layouts, and technical details align with your goals and the practical realities of construction. This avoids costly changes later in the project.

Planning Permission & Permitted Development Support

We guide clients through planning requirements, including permitted development checks and full planning applications where required. Our experience with local authorities across Kent and South East London helps ensure applications are prepared correctly from the outset.

Building Regulations & Compliance Management

We manage building control submissions and ensure designs comply with current regulations, helping avoid delays or issues during construction.

Pre-Construction Planning & Feasibility Advice

Before work begins, we assess feasibility, budgets, and timelines — helping clients make informed decisions early and avoid unrealistic expectations.

Liaison with Local Authorities & Consultants

We act as a central point of contact between clients, consultants, and authorities, ensuring communication remains clear and organised throughout the process.

Benefits of Professional Design & Planning Management

Avoid Delays, Mistakes, and Unexpected Costs

Proper planning reduces the risk of design issues, planning refusals, and last-minute changes that can increase costs.

Clear Direction from the Start

Clients benefit from a structured, step-by-step approach that removes uncertainty and keeps the project focused.

Better Design Outcomes

Coordinated design leads to spaces that work better practically, structurally, and aesthetically.

Smoother Construction Phase

Well-prepared projects run more efficiently on site, with fewer disruptions and clearer timelines.

Our process

Our Design & Planning Management Process

With over 30 years of experience, we take a structured, supportive approach to managing the design and planning stages of your project.

From early concepts through to approvals, our process focuses on clear communication, careful coordination, and practical guidance — helping ensure everything is prepared correctly before construction begins.

Initial Consultation & Project Overview

We begin by discussing your ideas, goals, budget expectations, and timeframe. This allows us to understand the scope of the project and the level of design and planning support required.

Site Review & Feasibility Assessment

We assess the property or site, identifying planning constraints, design opportunities, and structural considerations that may affect the project.

Design Coordination & Technical Development

We work alongside architects and engineers to develop drawings and specifications that are practical, compliant, and aligned with your vision.

Planning & Approval Management

Where planning permission is required, we manage the submission process, respond to queries, and coordinate any revisions needed.
‍

Pre-Construction Preparation

Once approvals are in place, we finalise technical details, schedules, and construction planning to ensure the build phase runs smoothly.
‍

Ongoing Support into Construction

Our involvement doesn’t stop at approval. We continue to support the project through the transition into construction, ensuring continuity and clarity.
